Outlook Paste Focus di Andrew Haskell

A lightweight Firefox extension that prevents the extra browser Paste prompt in Outlook on the web, while keeping Microsoft's Paste options (Ctrl) control available.

When Outlook triggers Firefox's clipboard confirmation after content is already pasted, typing can stop until you press Escape or click back into the message. This extension prevents the redundant request that causes that interruption.

• Works automatically in the message editor.
• Runs only on outlook.cloud.microsoft and outlook.office.com.
• Supports Ctrl/Cmd+V, Shift+Insert, and native paste events.
• No clipboard reading, data collection, network requests, or background service.
• No dependencies or build step required to use the extension.
